  1. Algebraic geometry of delta-matroids
  2. Nonvanishing criteria for local h-polynomials
  3. Geometry of polymatroids


I gave a talk about invariants of delta-matroids. The talk was aimed at experts.


I've written some code in Sage to compute certain intersection numbers on the Deligne-Mumford-Knudsen moduli space of stable curves of genus 0 with marked points, which we called "Kapranov degrees" and studied in this paper. The code can be found here.
